This interactive visualization links a world map of migrant deaths with a time-series histogram, filtering the map’s bubbles by brushing over dates. Built with React and D3 v5, it uses `geoNaturalEarth1` and `geoPath` for the map, `scaleSqrt` for bubble sizes, and `brushX` to select date ranges. The scatterplot-like map marks cities with circles whose radii reflect total dead and missing, while the histogram bars aggregate monthly totals. Data comes from the Missing Migrants Project subset, with country boundaries from World Atlas TopoJSON, and rendering uses SVG with `useMemo` for performance.
